Bible: 1 Samuel 13:19-22
13:19 A blacksmith could not be found in all the land of Israel, for the Philistines had said, “This will prevent the Hebrews from making swords and spears.” 13:20 So all Israel had to go down to the Philistines in order to get their plowshares, cutting instruments, axes, and sickles 1 sharpened. 13:21 They charged 2 two-thirds of a shekel 3 to sharpen plowshares and cutting instruments, and a third of a shekel 4 to sharpen picks and axes, and to set ox goads. 13:22 So on the day of the battle no sword or spear was to be found in the hand of anyone in the army that was with Saul and Jonathan. No one but Saul and his son Jonathan had them.
